Are you one of those people who can’t live without watching videos on YouTube or similar everyday? Would you like a simple a fast way to grab and download your favorite videos from major sharing sites?

NetVideoHunter is a Firefox add-on, that you can use to instantly download videos and music from almost all video-sharing sites, supporting Youtube, MySpace Music, Google Video, Metacafe, Dailymotion, Break, Putfile, iFilm, Videoegg, Veoh, Blip.tv, and more.

Here the video-instructions:

• Click here to Install NetVideoHunter inside your browser. The installation package comes in XPI formats, so if your Firefox version is older than 3.0 you might like to have an idea on how to install XPI files
• Go to the page where the video player is and play the video (if not started automatically)
• When the streaming begins, NetVideoHunter captures the videolink (when possible), and the video counter on the lower-right corner of the Firefox window is incremented, notifying you that a new file is ready for download
• You can then click on the NetVideoHunter icon, and the download window opens with the list of the captured videos and music.
